GPS Atoms Addition

Browse Source 
Porting gps location status (success/failure) logging to atom
GpsLocationStatusReported will be used by 2 count metrics to
determine the location failure rate.

Porting gps time to first fix seconds logging to atom
GPsTimeToFirstFixReported will be used by a value metric to determine
the average time to first fix on a GPS signal.

CTS tests will be added for these atoms in subsequent CL

Test: On Device using test script and gnsslogger.apk
>  make statsd_testdrive
>  ./out/host/linux-x86/bin/statsd_testdrive <ATOM_ID>
